Infection-fighting robot for hospitals

A new robotic cohort has been introduced to help eliminate viruses and superbugs. The system has three towers which uses ultraviolet light to disinfect hospital rooms. The technology, called the Surfacide Helios system, takes about 10 to 30 minutes to disinfect each room. The system uses laser mapping to ensure every exposed surface is covered. Olathe Medical Center, USA, uses three towers emitting UV light to eliminate superbugs and viruses from its hospital rooms.

Following the discharge of patient, the room is cleaned and the ultraviolet-C system is brought in kill pathogens that might remain. Even the surgical suites can be treated with UV-C at night when the cases are done for the day.

A strain of staph bacteria, MRSA is resistant to many of the antibiotics used to treat infections, and if left unchecked, can develop into sepsis. The American Journal of Infection Control last year found that UV-C reduced the environmental contamination of MRSA from 34.3 per cent to 3.3 per cent. The study also showed the elimination of C. diff, a spore-forming organism that is difficult to kill with most antibacterial cleaning products.
